The Aphex 300 “Compellor” is a combination compressor and peak limiter that transparently and intelligently controls inconsistencies and varying levels in an audio system by analyzing the incoming audio and making all the control adjustments automatically on a real-time basis for inaudible and continually optimized dynamic range control.

The Aphex Expressor 651 is a one-channel rackmount line-level compressor with SPR and Easyrider setting and Tubessence circuit – ideal for controlling a single instrument or voice channel.

The Aphex 720 Dominator II is a stereo multiband peak limiter providing greater limiting depth resulting in higher loudness with maintained audio quality – featuring an output adjustable over 34db in 0.2db steps and switchable operation of 10dBV/+4dBu/+8dBu.

The Aphex Expressor Model 9651 features High Frequency Expander technology that allows you to use higher compression ratios – even up to 50 to 1 – without worrying about “dullness” artifacts – and also features Sidechain Controls for cutting low frequency or applying a soft-knee threshold.

The Avalon AD2044 is a Dual Mono-Stereo Pure Class A Opto-Compressor featuring variable attach and release controls plus side chain access to deliver transparent non-invasive creative control from soft compression to hard limiting.

The Avalon VT737sp Tube Channel Strip is a 2-rackspace combo providing three Class A preamp input selections – an opto-compressor with minimum signal path – and sweepable EQ with hardwired bypass – bringing a new standard to creatively controlling high end audio

The Avalon VT-747sp combines a creative stereo tube-discrete Class A spectral-opto-compressor with a musical 6-band program equalizer – L-R output level and gain reduction metering – and internal regulated power supplies – making it ideal for high performance DAW input signal conditioning and analog mastering applications.

The BSS DPR402 2-Channel Compressor / Limiter is a high frequency de-esser and wide band de-esser with features such as peak limiting – adjustable speed – dynamic program manipulation – and full LED metering for both input and output.

The Chandler Limited TG1 is a recreation of the classic EMI TG12413 Limiter used in Abbey Road and EMI recording and mastering console from the late '60s - featuring an all discrete circuit with transformer balanced input and output - and a limiting element that produces smooth pleasing distortion with a warm open sound.

The DBX 1066 Dual Compressor / Limiter offers 2-channels of Selectable Classic or Manual DBX with essential noise gate and THD performance specs - along with features such as sidechain and true RMS power summing.

The DBX 160AD Compressor / Limiter features the same classic sound and easy set-up with uncompromised metering that is expected from DBX - it's fully compatible with +4/-10db and balanced/unbalanced systems - and includes the unique "Infinity + inverse-compression mode that decreases the audio output level below unity gain when the input exceeds threshold - ideal for controlling runaway house mix levels.

The DBX 162 is a 2-channel compressor/ limiter that uses a transformerless solid-state design and provides a rich tone that makes it great for drums, vocals, bass. and more.

The DBX 166XL Compressor / Limiter / Gate provides superb sonic performance without undesirable processing artifacts – featuring gate timing algorithms for smooth release characteristics and stereo or dual mode operation – as well as balanced inputs and outputs on ¼” TRS and XLR and program-adaptive expander/gates

The DBX 903 Compressor features three controls – threshold, compression ratio, and output gain – along with the familiar DBX “Over Easy” style knee shape and excellent metering dynamics.

The Fairchild 660 Compressor / Limiter is an iconic dynamics processor well-known for its special sound character – its use on Beatles recordings is legendary and helped to establish it as a classic choice in music-production around the world.

The Fairchild 670 is a legendary Tube Compressor / Limiter well-known for its dynamic control – processing 2 stereo channels either as a L/R stereo pair or as lateral and vertical components for stereo disk cutting – essentially, making records louder with less distortion by maximizing the use of the stereo groove space.

The GML 8900 Dynamic Range Controller is a 2U two-channel unit that progresses beyond mere electrical response – featuring multiple true-RMS detectors and remarkably accurate log converters with fast peak detectors to respond intelligently to real signal energy.

The Manley Variable MU Limiter Compressor is a tube and transformer-driven flagship compressor that adds clarity and cohesion to stereo buses or your entire mix – featuring flat frequency response from 20Hz – 25kHz and balanced inputs and outputs with fully differential all-tube circuitry.
